Abstract: Systems and methods of creating reference template images for detecting and recognizing products at a product storage facility include an image capture device having a field of view that includes a product storage structure of the product storage facility, and a computing device including a control circuit and being communicatively coupled to the image capture device. The computing device obtains images of the product storage structure captured by the image capture device, analyzes the obtained images to detect individual ones of the products located on the product storage structure. Then, the computing device identifies the individual ones of the products detected in the images and crops each of the individual ones of the identified products from the images to generate cropped images. The computing device then creates a cluster of the cropped images, and selects one of the cropped images as a reference template image of an identified individual product.

Abstract: A surge arrester (1) includes varistor elements (2) forming a stack (3) and having opposed end surfaces (4a, 4b). The varistor stack is electrically connected via the opposed end surfaces to end terminals (7a, 7b) having circumferential ridges (32a, 32b), which, in the event of failure of the varistor elements, are designed to relocate the resulting arc and direct it in a manner which reduces or minimizes damage to the surge arrester. The ridges serve as damage-tolerant sacrificial rooting points for an arc in the event of varistor element failure by presenting a substantial metal mass for the arc to erode away.

Abstract: A surge arrester has end terminals having circumferential ridges, which, in the event of failure of varistor elements of the surge arrester, are designed to relocate the resulting arc and direct it in a manner which reduces or minimizes damage to the surge arrester. Grooves lead from the inner surface of the terminals to the ridges, to facilitate arc relocation.

The varistor stack is electrically connected via the opposed end surfaces to end terminals having circumferential ridges, which, in the event of failure of the varistor elements, are designed to relocate the resulting arc and direct it in a manner which reduces or minimizes damage to the surge attester. The ridges serve as damage-tolerant sacrificial rooting points for an arc in the event of varistor element failure by presenting a substantial metal mass for the arc to erode away.

The unique structure enables the device to be clipped onto a variety of surfaces particularly in the user's kitchen to enable the convenient unloading of bags by users.

Abstract: A surge arrester has a single varistor element or a stack of varistor elements held between two end terminals by a plurality of elongate strength members disposed therearound. The ends of the strength members are inserted into recesses in the end terminals. Crimping of the end terminals distorts the recesses sufficiently to hold the strength members firmly therewithin, but without shearing and crushing (or otherwise damaging) the strength members.

Abstract: A sealed vented surge arrester and method of manufacture is described wherein the valve elements are held under compressive loading while strength members including a moisture sealing void filling compound are pressed fit from the sides of the unit with a shed applied over it. The design achieves all the desirable features of tubular strength members with an ease of manufacture from utilizing half-shell or more members which can be applied from the sides along the longitudinal axis of the valve elements during manufacture to provide better void filling between the structural members and the valve elements.

Abstract: A solder delivery system has a continuous element of solder material adjacent to at least one polymeric layer, which is provided with window means to control the flow of solder. The layers, if there are more than one, may be separate pieces, or may be parts of a folded sheet or a tube of polymeric material. In use, the conductors to be soldered are placed adjacent to corresponding terminals of a substrate and the system placed in contact with and perpendicular to the conductors, with the window means towards the conductors. On the application of heat and pressure, the solder melts and flows toward the terminals, and solder bridges are prevented by the "window frames" which lie between the terminals.

Abstract: Wound capacitors have a resistive strip included as an integral part of the capacitor section or roll. End areas of the resistive strip are in physical and electrical contact with the electrode strips, respectively, the rest of the strip discharging electrical energy stored in the capacitor when it is disconnected from a source of power. The portion of the resistive strip between the end areas is electrically insulated from the electrode strips so that current flows along the strip between the end contact areas. In one embodiment, the resistive strip extends about the winding, and in a second embodiment the resistive strip extends transverse to the electrode strips and loops around the edges of the electrode strips and the separating dielectric strips at the end of the capacitor section. If the capacitors are impregnated, the impregnant improves the ability of the resistive strip to withstand the voltage that is applied to the unit and to withstand and dissipate the heat generated in the strip.
